Reaction Steps

A solution in methanol containing 5.31 g of 3-chloro-4-(2,6-dichlorophenyl)-1,2,5-thiadiazole, 1.91 g of copper powder and 1.97 g of cuprous chloride saturated with ammonia gas was placed in a stainless steel vessel. After sealing the vessel, the solution was stirred at 120° C. for 24 hours. After allowing the mixture to cool, insoluble materials were removed by filtration. The filtrate was concentrated and the residue was purified by silica gel column chromatography to obtain 2.19 g of 3-amino- 4-(2,6-dichlorophenyl)-1,2,5-thiadiazole.
